6x30 Dienstglas binoculars 'eso' + tab 'gkp 42'

A very good, honest combat used example of the early-war era 6x30 Dienstglas field binoculars as produced by Optische Werke G. Rodenstock, Munich, under the 'eso' maker code. 
 
Indeed also still fitted with the original leather button flap - clearly maker marked/dated 'gkp 42' - as well as remains of the neck strap stubs. 
 
The optics have some relatively minor internal dust, but are still functional in the present state. The H/6400 Strichplatte rangefinding reticule is still fitted. 
 
A very nice example of their type by one of the less commonly seen makers!
